Does a Third Arterial Conduit to the Right Coronary Circulation Improve Survival?

This single-center group retrospectively reviewed their experience (2004-2014) with at least two arterial conduits for triple-vessel coronary artery disease to assess the benefit of adding a third arterial conduit versus a venous conduit to the right-sided circulation.  A total of 167 propensity-matched pairs were compared.  In this small study comparing intermediate survival, no benefit of adding a third arterial conduit was appreciated (HR 0.72, p = 0.411).
